Book excerpt: Lake Mead--the most prominent U.S. reservoir by volume--has been facing the effects of a devastating prolonged drought since 1999, which caused the lake water levels to plummet. The crust around Lake Mead has been uplifting due to an unloading effect of the current drought in the western USA. This research analyzed the crustal deformation due to elastic loading and unloading caused by climate-related water mass variation in Lake Mead over the last decade. The Global Navigation Satellite System (GNSS) measures elastic loading deformation responses to hydrological mass variations near or on the Earth's surfaces. GNSS has been used as an independent measurement to distinguish between hydrological models. This research systematically studied the Correlation between water level changes and crustal deformation around Lake Mead using data from the space geodetic technique GNSS. Other loading impacts, such as atmosphere and non-tidal ocean loading effects, were modeled and removed to study the lake-water-induced loading displacement. My result showed that the modeled elastic loading deformation is generally consistent with GNSS observations in the vertical component but usually smaller than GNSS observations in the horizontal directions, indicating the potential missing hydrological water components in the Model. This study further investigated the impacts of variations of other water loads, such as regional soil moisture and local groundwater. To compare the modeled loading deformation with GNSS observations, I calculated the correlation coefficients (r). Among all the six sites, the comparison for the sites P006 and NVLM indicated a strong correlation between observed surface deformation and modeled surface deformation from soil moisture and lake loading. After subtracting the modeled loading deformation from the corrected GNSS observations, I also discussed the Correlation between the residual series and the local groundwater level change around Lake Mead. I primarily studied the seasonal variations of the groundwater and GNSS residual series after removing loading deformation, which indicates a poroelastic response of the Earth's surface to subsurface groundwater change.

This book was released on 2002-09-27 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern scientific investigations of earthquakes began in the 1880s, and the International Association of Seismology was organized in 1901 to promote collaboration of scientists and engineers in studying earthquakes. The International Handbook of Earthquake and Engineering Seismology, under the auspices of the International Association of Seismology and Physics of the Earth's Interior (IASPEI), was prepared by leading experts under a distinguished international advisory board and team of editors.The content is organized into 56 chapters and includes over 430 figures, 24 of which are in color. This large-format, comprehensive reference summarizes well-established facts, reviews relevant theories, surveys useful methods and techniques, and documents and archives basic seismic data. It will be the authoritative reference for scientists and engineers and a quick and handy reference for seismologists.Also available is The International Handbook of Earthquake and Engineering Seismology, Part B.

Download or read book Ancient Landscapes of Western North America written by Ronald C. Blakey and published by Springer. This book was released on 2017-10-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section
